Online test directory

For information regarding a test not found in our test directory, contact Client Services at 331-221-4422.

Medicare limited coverage

If it is likely that Medicare will not cover a test, your patient will need to complete an Advanced Beneficiary Notice (ABN) before the test is ordered. The ABN Form serves as a notice that there is reason to believe Medicare will determine the test to be medically unnecessary, and therefore, will not pay for it. A copy of the signed ABN Form must be submitted with the test order.

More information on ABNs and tests with limited Medicare coverage can be found in the current CMS website.

Genetic testing

When ordering genetic tests such as Maternal Serum QUAD Screen, AFP Amniotic Fluid, AFP Serum, Chromosome Studies, Products of Conception or Cystic Fibrosis, we ask that you complete a Genetic Test Form and forward it with the specimen.

Reflexed testing

A reflexed test is a secondary test performed when a primary test result is outside of established result parameters. These secondary tests are performed to confirm the primary results or enhance the patient's clinical picture.

For some tests, performing the reflexed test is considered common practice and does not require additional orders from the physician. Other reflexed tests, though they may be clinically relevant, are not automatically performed unless specifically requested by the physician, usually at the time of the initial test order.

Collection instructions and requirements

We’ll work closely with you through every step of the process, including specimen collection. You can expect accurate identification, quality results and timely reporting as your patient's specimens are monitored through our computerized tracking system from pick-up to delivery.
